71 4 This difficulty was overcome by using a more reactive diacyl peroxide, diacetyl peroxide, at 25”. Under these conditions the catalyzed hydrolysis of the organoborane became much less important, and yields of the 1,4- addition compounds as high as 90%, based on the organoborane, were realized. The following procedure is representative of these studies of the peroxide-catalyzed reaction. A 25-ml flask, fitted with an inlet carrying a rubber septum ...
